Performance characteristics of polyurethane coatings

Polyurethane coatings have a series of advantages: (1) The wear resistance of the paint film is very strong, which is outstanding among various paint varieties, so it is widely used as floor paint, deck paint, yarn tube paint, etc. (2) Some varieties of coatings (such as epoxy, chlorinated rubber, etc.) have good protection function but poor decoration; some varieties (such as nitro paint, etc.) have good decoration but poor protection. Polyurethane coatings not only provide excellent protection, but also have beautiful decorative properties. Therefore, high-grade woodware, pianos, large passenger aircraft, etc. mostly use polyurethane coatings. (3) The coating film has strong adhesion and can be made into an excellent adhesive like epoxy, so the coating film is excellent for various surfaces (wood, metal, glass, cement, rubber, some plastics, etc.). of adhesion.
